Title: Coupled film storage device
IPC: G11C11/14
Filed: 1967-01-05
Abstract: 1,099,980. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 5, 1967 [Jan. 14, 1966], No. 622/67. Heading H1T. [Also in Division H3] A coupled film magnetic storage device includes two anisotropic magnetic films 16, 18 between which is arranged a drive conductor 20, the hard axes of the films being parallel to each other and to the magnetic field generated by current in the drive conductor, a bias field 32 being applied in the hard axis direction to both films. As shown, the films are deposited on a conductive substrate 10 and a bit conductor 26 and magnetic keeper member 28 are provided. In the quiescent storage state the magnetization vectors in the two films lie in the same direction biased slightly away from the easy axis, flux closure being provided for both films by keeper 28. To write data a word current is passed through conductor 20. As a result an oppositely directed image current is induced in the substrate 10 and the magnetic fields set up tend to reinforce each other in film 16 and oppose each other in film 18. The drive current direction is selected so that the drive fields are in the same direction as the bias field in film 16. As a result, the magnetization vector in film 16 rapidly rotates to the hard axis. The flux from film 16 then closes through film 18 and assists the word drive field in switching the upper film along the hard axis. Bit current of the appropriate polarity is then supplied to bit line 26 to determine the digit to be stored in conventional manner. The period prior to application of the bit pulse may be used for destructive readout, using the bit line for sensing. For non- destructive read-out a smaller word drive current is used. The coupled films preferably have the same magnetic characteristics and thickness. The bias field may be provided by external coils or by means of a continuous conductor extending parallel to the word drive lines over the whole of a matrix plane in zig-zag fashion. Adjacent word drive lines are in this arrangement supplied with currents in opposite directions. The bias conductor may be positioned between the magnetic keeper and the digit lines.

Title: Improvements in means for withdrawing the exhaust from internal combustion engines
IPC: F02B25/00
Filed: 1929-01-08
Abstract: 325,659. Blanche, L. L. Jan. 8, 1929. Movable-abutment type; discharge and suction pipes and passages for pumps and exhausters.- To the exhaust pipe 8 of an internal-combustion engine is connected a pump comprising a rotary abutment 14 and a rotor 15 with a vane 21 which sweeps around the annular chamber 12 and in its rotation passes through the, gap 22 in the abutment 14. The pump is driven at three times the speed of crank shaft for a three cylinder engine. As the power piston 3 opens the ports 7, the first flow of the exhaust passes direct to the outlet 13 and to the atmosphere. As the rotation of the pump continues the residue of exhaust is withdrawn into the chamber 12 and in consequence a fresh charge is drawn into the power cylinder. The drive of the pump for other numbers of cylinders is varied to suit the exhaust periods. The volume of the pump displacement is designed to be equal to the cylinder volume.

Patent GB-643993-A (GB)
Title: Improvements in sawtooth current generators
IPC: H03K4/34
Filed: 1947-01-10
Abstract: 643,993. Saw-tooth generating circuits. MURPHY RADIO, Ltd., and FAIRHURST, H. A. Jan. 10, 1947, No. 926. [Class 40 (vi)] In a circuit for generating a deflecting magnetic field, a pentode 1 is arranged with its anode coupled by a step-down transformer 2, 4 to the screen grid, a correcting voltage being supplied to the suppressor grid from the screen. The flux variation in the transformer may be used to deflect a C.R. tube beam directly by making a suitable gap in the core, or deflecting coils associated with the tube may be connected to a tertiary winding on the transformer. Frequency and amplitude control are respectively effected by varying a resistor 13 in the screen circuit, which determines the rate of change of screen current during the scan, and the mean anode voltage. Distortion due to the impracticability of making the transformer winding reactances high compared with their reactances at frame frequency is compensated for by feeding a potential proportional to the integral of the screen current derived from the potentials across potentiometer 15 to the suppressor grid, producing compensation in the manner described in Specification 511,600. As this method of linearizing is not effective at the beginning of the scan a resistor 17 and capacitor 18 are also connected in the suppresor grid circuit so as to linearize this part of the scan. Synchronizing pulses are applied to the control grid of the valve,

Filed: 1986-06-09
Abstract: An improved lighting system (10) which in the preferred embodiment includes a cathode (12) having an external surface (34) being coated with a cathode outside film (40) for emitting electrons therefrom. A first anode (14) extends internal to the cathode (12) for heating the cathode (12) to thereby emit electrons from the external surface (34). A second anode (16) is positionally located external to the enclosed cathode (12) for accelerating the electrons emitted from the cathode external surface (34). A bulb member (18) encompasses the cathode (12), the first anode (14), and the second anode (16) in a hermetic type seal. The bulb member (18) has a predetermined gas composition contained therein with the gas composition atoms being ionized by the cathode emitted electrons.

Title: Video player/recorder for recording on a blank disk and method for home recording
Inventor: GREEN ROBERT CHARLES
IPC: G11B7/08
Filed: 1986-07-03
Abstract: A blank disc (12) for a home video player/recorder has two or more reference tracks (41, 42) that are formed with the precision of a factory record and under the controlled environmental conditions of disc replication in a factory. When the disc is loaded into the player/recorder for a write operation, the player/recorder reads the reference tracks and simultaneously samples the track error signal and stores the error signal values in the data store of a processor. During the actual write operation, the processor operates on the stored values to generate a control signal to position the write head to define a track that follows the shape of the two adjacent reference tracks in proportion to the spacing of the track (40) between the reference tracks. Thus the player/recorder follows the precision factory reference tracks in spite of track distortion that usually occurs in a home redorder and in a home recording environment, and the track distortion of the home recorded disc is limited to about the track distortion of a factory recording.

Title: Process and apparatus for recording and/or reproducing digital data on a record carrier and record carrier
Inventor: SCHROEDER ERNST F
IPC: G11B20/12
Filed: 1996-03-21
Abstract: In conventional recording processes, the digital data are recorded continuously from the beginning to the end of the track of the recording medium at a net data rate which is fixed in each case for the entire recording. The aim of the invention is to record and/or scan data on a recording medium with optional reading and writing access. Continuous recording of digital data is replaced by burstwise recording. As a result of the burstwise recording of the data, each burst forms a cluster on the record carrier. The data are preferably recorded in CD standard recording format at a data rate of 1.411 Mbits per second. Recording and reproducing of data on a re-recordable contactlessly scannable record carrier, for example a magneto-optical disk (MOD).
